Application filed .Tune 17, 1914. Serial No. 845,592.

rIVhis invention relates to an apparatusfor dispensing liquids and is herein shown as 'embodied in a soda fountain or apparatus to which it is particularly applicable.

The invention has for its object to provide an apparatus with means as will be described, for discharging into a glass or other receptacle by gaseous pressure, a measured or predetermined quantity of syrup or other liquid.

The invention provide an apparatus, with which any one of a plurality of syrups or other liquids may be vselected by the operator, and discharged into the glass orrother receptacle by a single operating device.

The invention alsohas for its object to provide simple, compact. eflicient and :inexpensive apparatus, as will be described.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a vertical section, with parts in elevation, of a soda fountain embodying -the invention.

or opening ,10, adapted to be closed by aVL valve 12, herein shown as a disk valve,which is guided in its movement within the vessel CZ by ribs 13, which may be'arranged on the quarter, and each of which is provided with a shoulder 14 to limit the upward movement' of the valve. The vessel Z is. designed to hold a predetermined quantity of liquid and is suitably supported within the. container` b, so that theliquid in the container can flow freely into the vessel Z in the absence of air pressure within the vessel d.

Y For sake of distinction,l the vessel d may be-designated a measuring cup. The liquid contents of the measuring cup are Vdesigned to be discharged from the cup by air or other elastic fluid under pressure, and for this purpose the cup d is provided with an air inlet pipe 16 and with a liquid outlet pipe 17. v Y

The air inlet pipe 16 terminates near the top of the cup, and the liquid outlet pipe terminates near the bottom thereof. TheY air inlet pipe is connected with means for forcing air or other elastic fluid into the Y cup, so as to displace (the liquid therein Vand cause the latter to be discharged at a given point. Vhen the air pressure is removed from the cup, the liquid vin the container' opens the valve 12 and flows into the cup. Inv this manner a predetermined quantity ofthe liquid in the container b can be de-4 livered therefrom.

In the present instance, the-liquid outlet pipe17- is shown as extended to a head 20.

whichis'located within easy reach of the operator and above the container and the air inlet-pipe 16 is extended to a plate 21 preferably of rubber. Vwith, which cooperates the outlet nozzle. 22 of an air pump 23, which 1s Yherein shown as Yofthe diaphragm tvpe. and comprises a casing provided with a fixed wall. 24 and with a movable diaphragm or V piston 25, which forms a movable wall `of `the pump casina. rllhe diaphragm 25 is ino', by a handle 26 having pivoted to it a cylindrical steml 27 Vattached Vto the diaphragm, and movable on a guide rod 28 attachedto 'the fixed wall of the casing.

Bv moving the'handle 26 in the direction f the arrow 30 in Figs. land 3, the diaphragm piston 25 is moved toward the fixed means consists of a vessel (Z, see Fig. 41 wall2 and the air in the casing is forced which is provided in vits bottom'witha port Aout through thenozzle 22, and through the" air inlet pipe 16 into the cup d, wherein it forces the contents of the cup up through the outlet pipe 17 and into a glass or other receptacle, not shown, which is held by the operator in proximity t0 the head 20, but need not and preferably Will not be in contact with said head. On the return or back- Ward movement of the diaphragm piston, the air tight joint between the nozzle 22 and the plate 21 is broken, and the cup cl is again filled with liquid from the container b, which flows through the port or opening 10, the valve 12 being automatically opened by the liquid, and if desired, the liquid may be assisted by a spring, not shown, in opening the valve. The liquid in the outlet pipe 17 runs back into the cup d.

The invention as thus far described may be embodied in an apparatus having a single liquid container b and a measuring cup (Z Within the same, but it is especially applicable for use in an apparatus in which a plurality of liquid containers are used, to hold diiierent liquids, such for instance as different Syrups.

In the present instance, the invention is embodied in a soda fountain or apparatus, and provision is made, whereby a single air pump may be employed for forcing a measured quantity of liquid from any one ot a series of liquid containers, For this purpose, the air pump 23 is bodily movable with relation to the air inlet pipes 16 leading from the terminal plate 21 to the meas uring cups (Z Within the several containers b. To this end, the pump casing is connected with a sleeve 31, mounted to turn on a stationary pin 32 suitably supported Within the chamber c in which the pump is located, (see Figs. 3 and 7).

In the present instance, the pump casing 23 has secured to it arms 34e, which are pivotally mounted on a pin 35 extended through a sleeve 36 soldered or otherwise fastened to the sleeve 31 at iight angles to the latter, so as to allow for a suiilcient'movement. of the pump casing toward' and away from the terminal plate 251, to bring the nozzle 22 into contact with said plate and thereby make an air tight joint therewith and establish connection of said nozzle With a selected inlet pipe 16, and to break the said connection, when it is desired to connect the pumpV with the inlet pipe of another oontainer. Provision is made for returning the handle 26 to its starting position when released b y the operator, and for this purpose,

a springe, which is coiled about the pivot 41 for the handle, is employed in a manner Well understood. The handle 26 is fast to the pivot pin 41, which is supported by a sleeve 4t2 attached to the sleeve 31.

Provision is made for insuringv the proper connection of the pump with the air inlet pipo of the selected container, and for this purpose, the chamber 44 in which the pump is located, is provided a plate 45 having a plurality of slots 46, see Figs. 1, 3 and 5, one for each container, and into each of Which slots, the handle 26 is adapted to be moved, when the pump is to be operatively connected with the selectedV container to force air thereinto. In Fig. 5, the selective plate 4:5 is shown as provided with eight slots, and the terminal tube plate 21 with eight air inlet tubes. The plate 21 is separated i'rom the rear Wall of the chamber' 44, a suilicient distance to afford free movement of the handle laterally ot' the chamber. In Some instances, it may not be desired to discharge the full capacityv of the measuring cup, but only a desired proportion thereof, as for instance one half, one quarter, etc. To accomplish this result, I have provided a sto-p for the forward movement of the handle, in the form ot' a button 150, which may and preferably will be adjustable in each slot 4:6, when secured in its adjusted position, arrests the handle in its for-l ward movement and .tliol'obv limits the amount of air which is forced into the measuring cup, and thereby limits the quantity of liquid discharged into the glass or other receptacle- Provision is made for conveniently asseiny bling the inlet and outlet pipes 16, 17, and forA this purpose the inlet pipe 16 for each container is made in two sections and the outlet pipe 17 in two sections, which are joined together liquid tight by a coupling, comprising as herein shown a member 50, see Fig. 2, having holes through it, into which the upper sections of the pipes 16, 17 are inserted, and a second member 51 having similar openings for the reception of the lower sections of said pipes, as represented in Fig. 3. The holes in one coupling meni-V ber `50 communicate with. tho holesny the other member 5l, through holes. in a layerk 520i rubber or other packing material, and

the pipe sections may be soldered orother- Wiso lirmly secured, liquid tight in the said Sockets.Y

In the present instance the coupling mein- Y screws being carried by depending arms 5 6 f' attached to the upper member 50.

The upper sections of the outlet pipes 17, are led up to. the head 20 as herein shown,

and the latter is inclined and located above the' upper end of thev inlet pipes, which avoids vdripping of the liquid when the pressure removed, as the. liquid the out- 13ol l V C. s. WILLIAMSON. MEANS FOB HANDLING COAL.
